WICK TYPE REMOVABLE OIL BURNER Joseph F. Coscia, Waterbury, Conn.

Application August 27, 1946, Serial No. 693,366

burners of the wick type used in domestic heating plants, ranges, and the like.

One object of this invention is an oil burner of the above nature wherein the burner shells are removable as a unitto facilitate-cleaning.

Another object is to provide a device of the above nature in which the burner shell unit may be. removed without disconnecting any of the other burner fittings.

Another object is to remove the burner shells without the risk of oil leaks around the burner fittings. T I I Another object is to produce an oil burner which: will be simple, compact, inexpensive to manufacture, easy to manipulate, and very efficient and durable in use.

With these and other objects in view, there has been illustrated in the accompanying drawings one form .in which this invention may conveniently be embodied in practice.

In the drawings comprising two sheets of four figures, numbered Figs. 1 to 4, inclusive:

Fig. 1 is a plan view of a twin oil burner embodying my invention.

Fig; 2 is a side view of the same.

Fig- 3 is a plan view of one Of the oil burner units.

Fig. 4 is a vertical cross sectional view, taken along the line 4-4 of Fig. 3, looking in the direction of the arrows.

Referring now to the drawings in which lik reference characters designate corresponding parts throughout the several figures of the drawings, the numeral I indicates a pedestal bottom having a squared shell ll adjustably supporting the squared shaft ll of the H-shaped burner base support I8. The pedestal bottom It! may, if desired, be attached to a stove or the like by 'means of a bolt 16. A series of knurled adjusting screws l2, l3, l4, and I5 carried by the squared shell |I engage the sides of the squared shaft I! to lock the base support I8 at any selected height adjustment relative to the squared shell ll.

As best shown in dotted lines in Fig. 1, the

.-5 Claims. (Cl. 158-88) H-shaped twin burner base support I8 is prowalls '65, 66, 61, 68, and 69 projecting 'upwardsi from said burnerplate'to' form a central oil chamber 32, and a series of annular channels 34, 3|, 33, and 36 concentric with the chamber '32.-

The bottom of thecen tral chamber 32 is provided with a central rectangular opening adapted to receive a fountain or jet 26-through which the; fuel oil is fed into the 'centraloil chamber 32." from the 'oil supply pipe 25.

A plurality of radially disposed ducts 6|, 62, 63, and 64 extend through the walls of the cen-- tral chamber 32, the channels 34, 3|, 33, and 3D" to feed the fuel oil supplied by the fountain 26: from the central oil chamber 32 to-the inner and outer wick channels 3| and 30.

The radially disposedductstl, 62, 63, and64 subdivide the inner wick channel 3| into a series of arcuate compartments adapted to receive aseries of inner arcuate wicks 43, 44, 45,- and 46, substantially conforming in cross section to the shape of the compartments which house the inner wicks; x

t The outer wick channel 30 annular in cross section and is adapted to'accommodate an annular outer wick 42; The lower end of each arcuate inner wick 43, 44, 45', and 46, 'and of the annular outer wick 42, absorbs oil supplied to their respective wick channels 3| and 30 from the central oil chamber 32 by way of-the radially disposed ducts 6|, 62, 63, and 64.

, As best indicated in Fig. 4, the bottom plate of p the burner base casting 29 constitutes the bottom Thejzupper'end of eachannularpartition wall which rings the central oil chamber 32, the wick; channels 3| and 30, and the air passages 34'. and 33, may be rabbetted :or otherwise formed; to form an annular seat for a cup-shaped cover- 41, a central sleeve 52, and its associated con centric. sleeves 54, 55; 56, and- 51, respectively; The cover 41 is imperforate and serves to seal, ofi the central oil chamber 32 from the atmos-- phere, but the. sleeves '52, 54, 55, 56, and 51 are perforated to freely admitthe airdrawn through. 1 the outer andinner air ductslor inlets 33 and The outer 1 3 3| into the inner and outer wick channels 3i and 30.

. The oil chamber cover 41 is provided with radially disposed arms 48, 49, 50, and (see Figs. 1 and 3) adapted to seat themselves against 5 the radially disposed seats 60 (Fig. 4) rabbetted or otherwise formed in the upper edges of the walls of the radially disposed ducts 6|, 62, 63, and 64 to sealltheavaporized"oilz insaicr ducts;

A perforated-cup-shaped cover 53-is remov- 10 ably seated upon the central sleeve 52. Similarly,

a pair of concentric cover ring plates 58 and 59 enclose the upper ends of.the-pas,sag eways.. 34 and 33, respectively. The sleeves 5'4'and' 56" are preferably offset inwardly at their-supper ends to provide annular seats fonthevring plates 58. and 59 (see Fig. 4).

Each burner base 29 and its associated 5e;- ries of covers 41, 53, 58: and 59, and its perforated sleeves 52, 54, 55m 56;. and 51 constitute a distinct unit, which.,,is adapted totbe detachably supported,by the-,burner base sup-U port l8;

While there has been disclosed in this specifica:

tion one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not limited to the specific disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new, and for which it is desired to secure Letters Patent, is:

1. In an oil burner, a basesupport, an upwardly-extending oil fountain fixed upon said base support, a burner unit detachably secured to said base support comprising a burner plate having a plurality of annular spaced partition walls extending upwardly therefrom, said partition walls constituting a wick channel and enclosing a central chamber, a duct interconnecting said chamber and said wick channel, a cover closure for said central chamber and said duct, a perforated shell detachably supported by the outer wall of the wick channel, said burner plate having an opening in the bottom of the central chamber, said fountain projecting loosely through said opening into said central chamber, and means to prevent the escape of oil through said opening.

2. In an oil burner, a base support, an oil fountain secured to and extending above said base support, a burner unit comprising a burner plate having a plurality of annular partition walls concentrically arranged in spaced relation, said walls in conjunction defining a wick ohannel surrounding a central chamber, a radial duet interconnecting said central chamber and said wick channel, said burner plate having an elongated opening in the bottom of the central chamber, said base support detachably carrying 4 said burner plate with said opening loosely re: ceiv ns sa d on f unta n. and means f r ck n said burner unit to said base support to hold said cil fountain within said central chamber.

3. In an oil burner, a base support, a burner unit comprising a burner plate having an oil chamber, means for detachably supporting said burner unit on said base support, said oil chamber having an elongated opening in the bottom thereof, and a T-shaped oil fountain secured to said base support and projecting upwardly through said elongated opening, said fountain overhanging the sides of said opening, and adapted to pass through said opening when the fountain is turned to align vertically with the opening, whereby the burner unit may be readily applied to and removed from the base support without disturbing any oil supply connection of the burner.

4. The invention as defined in claim 3, in which said elongated opening is provided with an upstanding rim, the upper portion of said oil fountain comprising downwardly inclined channelled ears overhanging said rim, whereby oil dropping from said ears will be prevented from escaping downwardly through said opening.

5. The invention as defined in claim 3, wherein said oil fountain is provided with a closely fitting slidable apertured plate covering said elongated aperture, and a spring urging said apertured plate against the lower surface of said burner plate, whereby the passage of air through said elongated aperture will be prevented.
